Arsenal are preparing a blockbuster bid for Vinicius Junior as uncertainty surrounding the Brazilian star's future at Real Madrid continues to grow, with stalled contract negotiations opening the door for one of the biggest transfers of the summer.

The reigning Premier League champions are closely monitoring the situation after Vinicius and Real Madrid failed to reach an agreement on a new contract despite nearly 18 months of negotiations.

With the 26-year-old entering the final year of his current deal, Arsenal are ready to capitalize if discussions between the player and the Spanish giants ultimately collapse.

According to Cadena SER, Arsenal are prepared to submit an offer worth 100 million euros ($116 million) plus an additional 20 million in performance-related bonuses.

While no formal bid has been made, the London club has reportedly received internal approval to pursue one of world football's most explosive attacking talents.
